There was a bang like a gunshot from the garage and now the door will not lift
A torsion spring has broken. That noise is the coil releasing its stored tension. Do not operate the door. Book a spring replacement — this is the textbook case.

Spring Repair in Boskruin
Garage door spring repair in Boskruin
Boskruin is a residential suburb of freestanding homes and complexes on higher ground in northern Randburg. Sloping driveways and wider doubles, with mid-life automation that has usually been left un-serviced for years.
That is the context garage door spring repair in Boskruin happens in. Complex doors in this area are the classic high-cycle case: several openings a day, every day, on doors that are all the same age because they were all fitted at once. When one unit's spring goes, its neighbours are usually not far behind, and we often service several doors in a complex on one visit.
This page covers what that means in practice — the faults we actually attend here, how the job is diagnosed and priced, and how quickly a technician reaches Boskruin. For the subject in full, see our garage door spring repair guide; for everything else we do here, see garage door services in Boskruin.

Scope of work
What garage door spring repair in Boskruin covers
Spring work is measured before it is quoted. The correct spring is a function of the door's weight, its height and the drum size it winds onto — get any of those wrong and the door will be over- or under-sprung, which shortens the life of the spring, the cables and the motor together.
Where a development has a standard door across every unit, we usually know which springs, board and remotes to bring before arriving — which is the difference between a first-visit fix and a second appointment.
- lift cables inspected at the same time, since a spring failure often damages them
- Cones, winding bars, centre bearings and end bearing plates replaced where worn
- Cycle-rated springs matched to how often the door is actually used, not the cheapest available
- Springs supplied in matched pairs, so both sides share the load and the cycle life
- Extension springs running alongside the horizontal tracks, typical of tip-up and older doors
Everything is quoted as a fixed price on site before work starts, and every repair and installation in Boskruin carries the same 12-month workmanship warranty as the rest of the footprint.
Real situations
What Boskruin customers describe, and what it usually means
These are the calls we take most often from Boskruin and the surrounding Randburg area.
The door is very hard to lift by hand with the motor disconnected
Under-sprung. Either a spring has failed, or the springs fitted were never rated for this door's weight. Have the door weighed and the spring specification checked, not just replaced like for like.
I replaced one spring last year and now the other has gone
The classic consequence of replacing a broken spring singly rather than as a pair. Replace as a matched set this time so the cycle life resets on both sides.
The door lifts skew, with one side leading the other
Uneven spring tension, or a cable that has slipped its drum. Stop using it. A skew door damages tracks and can jump its rollers.
Springs explained
What garage door springs do and why they fail in Boskruin
How a torsion spring actually works
A torsion spring sits on a steel shaft above the door opening. As the door closes, the cables wind onto drums at each end of that shaft and twist the spring, storing energy. When you open the door, the spring unwinds and returns that energy, lifting the weight for you.
Balance is the whole point. On a correctly sprung door you can stop it at waist height with the motor disconnected and it will simply stay there — neither falling nor rising. That single test tells a technician more about a door's condition than any electronic diagnostic.
Torsion springs versus extension springs
Torsion springs are the modern standard on sectional doors: mounted centrally, wound under controlled tension, and safer in failure because the spring stays captive on its shaft.
Extension springs stretch along the horizontal tracks and are still found on tip-up doors and older installations. They do the same job less elegantly, and when one breaks it can travel — which is why safety containment cables through the centre of an extension spring are not a nice-to-have.
Both types are fitted and replaced. What we will not do is fit a torsion conversion to a door that does not have the headroom for it, or leave an extension spring without its containment cable.
Why garage door springs break
Springs fail from fatigue, not from abuse. Every open-and-close is one cycle, and a standard spring is rated at roughly 10,000 of them. A household opening the door four times a day reaches that in about seven years; one opening it ten times a day gets there in under three.
Three things accelerate it. Rust, which pits the steel and creates a stress point — the reason a light oiling once a year genuinely extends spring life. Incorrect sizing, where a spring that was never right for the door weight has been fighting from day one. And imbalance, where a worn partner spring, dragging rollers or a bent track make the surviving spring work harder than it was rated to.

How it works
The garage door spring repair process in Boskruin
The same order on every job, whether it is a single household door or a run of doors in one complex.
- 01
Weigh and measure
Door weight, drum size, wire gauge and spring length are established before a part is chosen.
- 02
Secure and release
The door is clamped in position and the remaining tension is released with winding bars.
- 03
Replace as a pair
Both springs go on together, with cones, bearings and cables checked and renewed where worn.
- 04
Wind to specification
The springs are wound to the calculated turn count, not by feel.
- 05
Balance and recalibrate
The door is balance-tested at three heights and the opener's force and travel limits reset.
Coverage
Getting a technician to Boskruin
Boskruin is a short run from our Sandton base, so emergency call-outs are typically attended within 20 minutes and standard bookings are same or next working day.
Because the doors here were installed together, they age together. It is worth asking neighbours whether theirs are showing the same symptoms — a block visit across several units costs considerably less per door than the same jobs booked separately over a year.
The same run covers Randburg, Northcliff, Blairgowrie and Parkhurst, so a technician already working nearby can often be routed to Boskruin the same day. If your suburb is not listed, it is worth calling — the Randburg service area extends beyond the pages published so far.
Anything that leaves a property unsecured is dispatched ahead of standard bookings at any hour — see emergency garage door service.

FAQ
Spring Repair in Boskruin: common questions
Do you replace broken garage door springs in Boskruin?
Yes, and it is the most common job we do here. Torsion and extension springs for Boskruin doors are carried on the van in the common sizes, so most spring replacements are finished on the first visit. Boskruin is a short run from our Sandton base, so emergency call-outs are typically attended within 20 minutes and standard bookings are same or next working day.
My spring broke and my car is locked in — can you come out to Boskruin now?
Yes. A trapped vehicle is treated as an emergency in Boskruin at any hour, including weekends and public holidays. Do not try to force the door in the meantime — on a broken spring it is unsupported and can drop.
How long does a spring replacement take in Boskruin?
Typically 60 to 90 minutes on site once the technician arrives, including weighing the door, fitting the matched pair, re-balancing and resetting the motor force. Boskruin is a short run from our Sandton base, so emergency call-outs are typically attended within 20 minutes and standard bookings are same or next working day.
Why do garage door springs break so often in Boskruin?
Cycle count. Doors in Boskruin are often opened many times a day, which uses up a standard spring's rated 10,000 cycles in a fraction of the years a low-use door would take. High-cycle springs are usually the better specification here.
Should both springs be replaced on my Boskruin door?
On a dual-spring door, yes. Both were fitted together and have the same cycle history, so the surviving spring is weeks or months from failing. Replacing the pair once avoids a second call-out in Boskruin and keeps the door balanced.
Can you check the springs on other doors in my Boskruin complex or street?
Yes, and it is worth asking. Doors fitted at the same time in the same development reach the end of their spring life at the same time, so we regularly check and replace several doors in one Boskruin visit at a lower cost per door.
Do you also handle spring repairs near Boskruin?
Yes — Randburg, Northcliff, Blairgowrie and the rest of the Randburg area are on the same run, so a technician already carrying spring stock nearby can often reach you the same day.
